Hi There,
I have a session in my main window. Freom here, I want to open a
popup, load a page and access the $_SESSION[] array but I seem not
able to in my pop up.
<?php
session_start();
var_dump($_SESSION);
?>
at the top of my popup script just prints
array(0) { }
and this is what the session dumps on the page from where I open the
popup:
string(2) "10"
Why is that? What's going on here, I seems to recall that i used this
before and it worked just fine - any clues?
Thank you!
Ron

Are you outputting ANYTHING - including whitespace - before the call to
session_start()?
Is the popup accessing the same domain as the main window?

No,
In both files, the first characters are:
<?php
session_start();
> Is the popup accessing the same domain as the main window?
Yes, they're both on the same domain, different directories tho but
that shouldn't matter, would it?

<?php

echo session_id();
Now I tried passing the session id along as a get variable and in my
pop up script it now says
<?php
session_start();
echo $_GET['sessionid']."<br/>";
session_id($_GET['sessionid']);
echo session_id();
?>
On top. I confirm that the session id gets set to the correct value
but I still can't retrieve my UserID value from the session variable.
Something seems to be majorly messed up... :(

I do use it like an array: $_SESSION['userid']

I'm currently not using cookies, I'm passing the sessionid as a get
variable to the script and set it like:
session_id($_GET['sessionid']);
session_start();
echo $_GET['sessionid']."<br/>";
echo session_id();

Then most likely the SID gets lost when you open your pop-up. In cases
like this you would have to manually append the predefined constant
'SID' to your URL. See the manual for details. [1]
But the better and recommended way would be to use a session cookie -
that's what cookies are for. SIDs in URLs are a security risk, because
they're stored in logfiles and in HTTP Referrer headers, which exposes
the SID to other people and might allow session hijacking. [2]
So better use a cookie instead, which is safer and should also solve
your problem. Also change these configuration options:
session.use_trans_sid = 0
session.use_only_cookies = 1
to prevent PHP from automatically rewriting URLs.

So Thanks for everyone's feedback. I suddenly started to work as
expected which is very confusing to me and to me... I can not tell
what made this happen... I went as far as rebooting Windows, trying
different browsers and and and.... and then it suddenly... just
worked... :o Very strange and kinda scary!
Thanks for everyone's feedback anyways, it is much appreciated!
Ron

$_SESSION is an array, not a string, so the funny thing is that it's
only working as expected in the popup window :)
